Broadband aeronautical burst data transmission in 4DT navigation

The Four-Dimensional Trajectory (4DT) navigation depends on the efficient interaction with the terrestrial Ground-Station (GS) on the waypoint. A considerable amount of the data, i.e., Aeronautical Short Messages (ASMs), should be compacted and transmitted from the GS to the aircraft in a short-time. The traditional VDL-2 and L-DACS1 data links can not efficiently provide the 4D trajectory data link (4DTRAD) service with the burst and dense data packets. Therefore, in this paper, large Multi-Input Multi-Output (MIMO) with broadband aeronautical communication data link is proposed. Specifically, the massive MIMO NCI-OFDM transmission scheme with 4DT frame is proposed. Not only the high capacity and efficiency are achieved, but also the Quality of service (QoS) is maintained, such as packet delay and packet loss rate with the safety requirement.
